LT1461CCS8-5#TRPBF

Voltage Reference Overview

The LT1461CCS8-5#TRPBF is a micropower precision low dropout series voltage reference from Analog Devices, housed in an 8-lead plastic SO package. It provides a fixed 5V output with an initial accuracy of ±0.08% and a maximum temperature coefficient of 12ppm/°C. The device operates within a commercial temperature range of 0°C to 70°C, drawing a typical supply current of 35µA with a maximum of 70µA. It supports a minimum output drive current of 50mA and features a shutdown pin for power management.

Voltage Reference Feature Summary

• Advanced curvature compensation techniques ensure low temperature drift and high output accuracy.
• Integrated shutdown capability allows switching full load currents and enables system power down modes.
• Built-in thermal limiting protects the component from overload conditions during operation.

Voltage Reference Applications

• A/D and D/A Converters
• Precision Regulators
• Handheld Instruments

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the CCS8 grade matches the required ±0.08% accuracy and 12ppm/°C drift specifications. Ensure the commercial temperature range (0°C to 70°C) aligns with the application environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a fixed 5V reference with micropower consumption is required alongside moderate load drive capabilities. The C-grade offers a balance between cost and precision, suitable for systems where ±0.08% initial accuracy is sufficient. Consider the SO-8 package constraints and thermal management needs if operating near the upper limits of the specified temperature range.

Voltage Reference Part Context

This component belongs to the LT1461 family of bandgap references, which combines high accuracy with low supply current. The family includes various voltage options and accuracy grades, utilizing trimmed precision thin-film resistors. The LT1461 series is designed for applications demanding stability and low power consumption without sacrificing output drive performance.
